I could hardly believe your post when you told us that he deliberately threw something at your head in front of your mother !
Obviously, he's reverted back to his usual self and feels your ''little rebellion phase'' is over, so he's free to abuse you whenever or wherever he fancies ! (either that, or he's upping the ante because he's sick of pretending to be 'nice', and needs to get you back in your box asap cos he can't cope with the charade any more !)
Good grief but he's truly evil isn't he ?
Whatever you do, you must leave today, start your course, and make very sure he cannot get into your new home ! Until you get the locks changed, make very sure you keep the keys in the door (so he can't put a key in), click the lock set if it's a Yale lock, or bolt the doors.
Once he knows you're breaking free, he's got nothing to lose by being openly violent to try to ''bring you to heel'', so you need to be extra vigilant and careful. Block him on your phone/ email/ all SM and tell your Mum you have left him and to not speak to him when he contacts her too.
Do not let any threats/ unwanted visits/ attempts at contact go unanswered ! Tell the police you have left an abusive marriage, and phone them EVERY TIME !
You deserve to be happy, and you will be !
Enjoy every moment of your course, your freedom, and your new life without fear.
